Abstract
In an abduction-type motor having a divided core() formed by dividing a stator core into plural blocks and a motor stator having such a structure as the divided core may be reassembled, the motor has a coil winding framecontinuously formed a continuous unit of coupling parts, a part of which is flexible and made of insulation material, embedded into the individual divided cores, and a coilarranged and wound by supporting the divided core so that the teeth top parts of the divided core may be directed inside and located on a circle, in which its coil winding structure has the number of coil stages at the teeth top part (external peripheral part) of the divided core larger than the number of the coil stages at the internal peripheral part, and the diameter of the teeth top part of the divided core after assembly is identical to the diameter of the teeth top part while coil winding work, and the length of the crossover linebetween the coil windings is made enough to be equivalent to a single slot or more, not excessive or not insufficient.
